Asphalt shingles have which of the following characteristics?

The characteristic that asphalt shingles exhibit during fire conditions is that they can drip and run. When exposed to high heat or flames, asphalt shingles can begin to melt and lose their structural integrity, which leads to dripping. This behavior can create additional hazards during a fire, as molten material may fall from the roof and potentially ignite combustible materials below.

While it is accurate to say that asphalt shingles can produce some smoke when burning, they are not classified as producing "little smoke." Additionally, asphalt shingles are not considered non-combustible, as they are made from organic materials and petroleum products which are inherently combustible. Therefore, the option indicating that asphalt shingles drip and run under fire conditions highlights a crucial aspect of their behavior in a fire situation.
